Telegram or iMessage; which one is safer or has better security?

After enabling Apple’s Advanced Data protection, which one is more secure, iMessage or Telegram (default chat, not secret)

I’m curious because based on that I might take a decision for texting people. I am aware of multiple Telegram features which are better than iMessage, however my question is just for the privacy and security aspect. Thanks!

**Edit**: I know objectively Signal is better, I am aware. Right now I have these two options. No one uses Signal, I tried everything …
